La metodología cooperativa como instrumento de investigación en el diseño curricular para la adaptación de asignaturas en el espacio europeo de educación superior, en los ámbitos de enfermería y maestro de educación física

El objeto de estudio parte de un proceso de investigación acción (McKernan, 1999 y Eliot, 1993), el cual estamos llevando a cabo desde hace dos cursos, en el marco del plan piloto para la adaptación de los estudios de la UdG al Espacio Europeo deEducación Superior (EEES). La justificación se enmarca en la demanda del Espacio Europea de Educación Superior, mediante el desarrollo de una educación basada en competencias con el objetivo de partir de una información que responda a unas necesidades reales basadas del Proyecto Tunning. Esta aportación se refleja en una asignatura de libre elección de nuevaincorporación. Esta propuesta, da un énfasis especial en la interacción entre los dos estudios: educación y enfermería. La cooperación interdisciplinar nos ha permitido compartir, interactuar y dialogar de forma crítica para poder seguir avanzando en nuestra propuesta. Estamos plenamente convencidos que la Educación Física bien dosificada, la alimentación cualitativamente equilibrada y unas condiciones higiénicas correctas en un entorno favorable, son pilares de una buena educación para la salud

Genes for normal sleep and sleep disorders.

Sleep and wakefulness are complex behaviors that are influenced by many genetic and environmental factors, which are beginning to be discovered. The contribution of genetic components to sleep disorders is also increasingly recognized as important. Point mutations in the prion protein, period 2, and the prepro-hypocretin/orexin gene have been found as the cause of a few sleep disorders but the possibility that other gene defects may contribute to the pathophysiology of major sleep disorders is worth in-depth investigations. However, single gene disorders are rare and most common disorders are complex in terms of their genetic susceptibility, environmental effects, gene-gene, and gene-environment interactions. We review here the current progress in the genetics of normal and pathological sleep.

Hypoglycémie et traitement du diabète de type 2. Le retour à une normoglycémie n'est pas nécessairement la meilleure stratégie thérapeutique [Hypoglycemia and diabetes treatment: the return to normal glucose level is not always the best therapeutic strategy].

Recent clinical trials with type 2 diabetic patients and the quest of normal glyceamic values, have revealed difficulties and limitations. These too normal glyceamic targets corresponding to the physiological standards are associated with very high rate of hypoglycemia and an increase of mortality. A too simplistic view of treatment: "the lowest, the better is in the diabetes" is no longer defensible. The knowledge from complex systems behavior invites us to search targets adapted to a new state of equilibrium due to loss of self-regulation. These targets should not aim the physiological standards but to be adapted to patient's situation. Shared decision-making and consensus are the two pillars of this new strategy supported by the new ADA-EASD guidelines.

Block of the superior cervical ganglion, description of a novel ultrasound-guided technique in human cadavers.

OBJECTIVE.: Injection of opioids to the superior cervical ganglion (SCG) has been reported to provide pain relief in patients suffering from different kinds of neuropathic facial pain conditions, such as trigeminal neuralgia, postherpetic neuralgia, and atypical facial pain. The classic approach to the SCG is a transoral technique using a so-called "stopper" to prevent accidental carotid artery puncture. The main disadvantage of this technique is that the needle tip is positioned distant from the actual target, possibly impeding successful block of the SCG. A further limitation is that injection of local anesthetics due to potential carotid artery puncture is contraindicated. We hypothesized that the SCG can be identified and blocked using ultrasound imaging, potentially increasing precision of this technique. INTERVENTIONS.: In this pilot study, 20 US-guided simulated blocks of the SCG were performed in 10 human cadavers in order to determine the accuracy of this novel block technique. After injection of 0.1 mL of dye, the cadavers were dissected to evaluate the needle position and coloring of the SCG. RESULTS.: Nineteen of the 20 needle tips were located in or next to the SCG. This corresponded to a simulated block success rate of 95% (95% confidence interval 85-100%). In 17 cases, the SCG was completely colored, and in two cases, the caudal half of the SCG was colored with dye. CONCLUSIONS.: The anatomical dissections confirmed that our ultrasound-guided approach to the SCG is accurate. Ultrasound could become an attractive alternative to the "blind" transoral technique of SCG blocks.

Giant extra-hepatic thrombosed portal vein aneurysm: a case report and review of the literature.

BACKGROUND: Extrahepatic Portal vein aneurysm (EPVA) is a rare finding that may be associated with different complications, e.g. thrombosis, rupture, portal hypertension and compression of adjacent structures. It is being diagnosed more frequently with the advent of modern cross-sectional imaging. Our review of the English literature disclosed 13 cases of thrombosed EPVA. CASE PRESENTATION: A 50-years-old woman presented with acute abdominal pain but no other symptom. She had no relevant medical history. Palpation of the right upper quadrant showed tenderness. Laboratory tests were unremarkable. A computed tomography showed portal vein aneurysm measuring 88 × 65 mm with thrombosis extending to the superior mesenteric and splenic vein. The patient was treated conservatively with anticoagulation therapy. She was released after two weeks and followed on an outpatient basis. At two months, she reported decreased abdominal pain and her physical examination was normal. A computed tomography was performed showing a decreased thrombosis size and extent, measuring 80 × 55 mm. CONCLUSIONS: Although rare, surgeons should be made aware of this entity. Complications are various. Conservative therapy should be chosen in first intent in most cases. We reported the case of the second largest thrombosed extra-hepatic PVA described in the literature, treated by anticoagulation therapy with a good clinical and radiological response.

Hemodynamic, renal, and endocrine effects of 4-h infusions of human atrial natriuretic peptide in normal volunteers.

A synthetic human atrial natriuretic peptide of 26 aminoacids [human (3-28)ANP or hANP] was infused into normal male volunteers. Six subjects were infused for 4 h at 1-wk intervals with either hANP at the rate of 0.5 or 1.0 microgram/min or its vehicle in a single-blind randomized order. Human (3-28)ANP at the dose of 0.5 microgram/min raised immunoreactive plasma ANP levels from 104 +/- 17 to 221 +/- 24 pg/ml (mean +/- SEM), but it induced no significant change in blood pressure, heart rate, effective renal plasma flow, glomerular filtration rate, or renal electrolyte excretion. At the rate of 1.0 microgram/min, human (3-28)ANP increased immunoreactive plasma ANP levels from 89 +/- 12 to 454 +/- 30 pg/ml. It reduced effective renal plasma flow from 523 +/- 40 to 453 +/- 38 ml/min (P less than 0.05 vs. vehicle), but left glomerular filtration rate unchanged. Natriuresis rose from 207 +/- 52 to 501 +/- 69 mumol/min (P less than 0.05 vs. vehicle) and urinary magnesium excretion from 3.6 +/- 0.5 to 5.6 +/- 0.5 mumol/min (P less than 0.01 vs. vehicle). The excretion rate of the other electrolytes, blood pressure, and heart rate were not significantly modified. At both doses, human (3-28)ANP tended to suppress the activity of the renin-angiotensin-aldosterone system. In 3 additional volunteers, the skin blood flow response to human (3-28)ANP, infused for 4 h at the rate of 1.0 microgram/min, was studied by means of a laser-doppler flowmeter. The skin blood flow rose during the first 2 h of peptide administration, then fell progressively to values below baseline. After the infusion was discontinued, it remained depressed for more than 2 h. Thus, in normal volunteers, human (3-28)ANP at the dose of 1.0 microgram/min produced results similar to those obtained previously with rat (3-28)ANP. It enhanced natriuresis without changing the glomerular filtration rate while effective renal plasma flow fell. It also induced a transient vasodilation of the skin vascular bed.

Absence of the fourth cranial nerve in congenital Brown syndrome.

PURPOSE: To elucidate the aetiology of congenital Brown syndrome. METHODS: Four consecutive patients diagnosed with unilateral congenital Brown syndrome had a comprehensive standardized ocular motility examination. Any compensatory head posture was measured. Brain magnetic resonance imaging (MRI) with regard for the IV cranial nerve (CN) was performed in all patients. Orbital MRI was performed in 2/4 patients, with images acquired in eight directions of gaze and superior oblique (SO) muscle areas compared. RESULTS: CN IV could not be identified bilaterally in two patients, but was absent only on the side of the Brown syndrome in the two other patients. On the normal side, orbital MRI revealed a smaller SO muscle area in upgaze than in downgaze, demonstrating normal actions of this muscle. On the side of the Brown syndrome, the SO area remained the same in upgaze and in downgaze and approximately symmetric to the area of SO in downgaze on the normal side. CONCLUSIONS: These cases add further anatomical support to the theory of paradoxical innervation in congenital Brown syndrome. CN IV was absent in two patients on the side of the Brown syndrome, but without muscle hypoplasia. SO muscle size did not vary in up- and downgaze, which we interpreted as a sign of constant innervation through branches of CN III.

Interregional compensatory mechanisms of motor functioning in progressing preclinical neurodegeneration.

Understanding brain reserve in preclinical stages of neurodegenerative disorders allows determination of which brain regions contribute to normal functioning despite accelerated neuronal loss. Besides the recruitment of additional regions, a reorganisation and shift of relevance between normally engaged regions are a suggested key mechanism. Thus, network analysis methods seem critical for investigation of changes in directed causal interactions between such candidate brain regions. To identify core compensatory regions, fifteen preclinical patients carrying the genetic mutation leading to Huntington's disease and twelve controls underwent fMRI scanning. They accomplished an auditory paced finger sequence tapping task, which challenged cognitive as well as executive aspects of motor functioning by varying speed and complexity of movements. To investigate causal interactions among brain regions a single Dynamic Causal Model (DCM) was constructed and fitted to the data from each subject. The DCM parameters were analysed using statistical methods to assess group differences in connectivity, and the relationship between connectivity patterns and predicted years to clinical onset was assessed in gene carriers. In preclinical patients, we found indications for neural reserve mechanisms predominantly driven by bilateral dorsal premotor cortex, which increasingly activated superior parietal cortices the closer individuals were to estimated clinical onset. This compensatory mechanism was restricted to complex movements characterised by high cognitive demand. Additionally, we identified task-induced connectivity changes in both groups of subjects towards pre- and caudal supplementary motor areas, which were linked to either faster or more complex task conditions. Interestingly, coupling of dorsal premotor cortex and supplementary motor area was more negative in controls compared to gene mutation carriers. Furthermore, changes in the connectivity pattern of gene carriers allowed prediction of the years to estimated disease onset in individuals. Our study characterises the connectivity pattern of core cortical regions maintaining motor function in relation to varying task demand. We identified connections of bilateral dorsal premotor cortex as critical for compensation as well as task-dependent recruitment of pre- and caudal supplementary motor area. The latter finding nicely mirrors a previously published general linear model-based analysis of the same data. Such knowledge about disease specific inter-regional effective connectivity may help identify foci for interventions based on transcranial magnetic stimulation designed to stimulate functioning and also to predict their impact on other regions in motor-associated networks.

Práticas assistenciais em reanimação do recém-nascido no contexto de um centro de parto normal

Aproximadamente 10 a 15% dos recém-nascidos (RNs) apresentam dificuldades de adaptação ao nascimento, o que requer habilidade e prontidão dos profis-sionais para intervir nessas situações. Este estudo observacional, transversal objetivou descrever as práticas assistenciais empregadas em reanimação neo-natal em um Centro de Parto Normal de um hospital público de São Paulo. Observou-se 100 atendimentos prestados pela equipe profissional e os dados foram registrados em um instrumento checklist. A presença de líquido meconial foi constatada em 24 (24,0%) partos e a aspiração das vias respiratórias foi realizada em 47 (47,0%) RNs. Desse total, 3 (6,4%) tiveram a traquéia aspirada e 26 (26,0%) RNs receberam oxigenação, sendo que 5 (19,2%) com máscara aberta e pressão positiva. Massagem cardíaca foi realizada em 1 (1,0%) RN. Após a reanimação neonatal inicial, 6 (6,0%)RNs foram transferidos à UTI neonatal devido desconforto respiratório.

Centro de parto normal e a assistência obstétrica centrada nas necessidades da parturiente

Levando em conta os vários estudos e reflexões a respeito do novo modelo de assistência ao parto e nascimento (assistência humanizada), e trabalhando como enfermeira obstétrica em um Centro de Parto Normal, surgiu o questionamento a respeito desse conceito, devido às diversas conotações dadas a esse termo. Este artigo foi produzido com a finalidade de divulgar nossa proposta de substituição da expressão "assistência humanizada ao parto", por "assistência obstétrica centrada nas necessidades da parturiente", e de discorrer como essa assistência é prestada no Centro de Parto Normal do Hospital Geral de Itapecerica da Serra (SP), que segue um protocolo de condutas obstétricas e normas preconizadas pelo Ministério da Saúde.
